Expreview is the second site that writes that AMD's upcoming high-end RV790 will be nothing more than an overclocked RV770. Contrary to earlier rumors, it appears this upcoming high-end graphics card from AMD will still be a 55nm part, and not 40nm.
The site claims the RV790 will be named Radeon HD 4970, with a 950MHz core compared with 750MHz on the Radeon HD 4870. The memory clock will remain at 3600MHz GDDR5.
With massive 27% improvement of core clock, RV790 targets directly at GeForce GTX285. Maybe you would think AMD is confusing us on purpose like what they did to RV770, but the informer believe there won’t be much change in specs. The availability and pricing of RV790 are not disclosed yet, but hardware-info says it would be announced in April.
